EDWARD LAUTNER, or LAMAR, INDIANA.

FREIGHT-CAR DOOR.

To all whom it may concern:

Be it known that I, EDWARD LAUTNER, a citizen of the United States, residing at Lamar. in the county of Spencer and State of Indiana, have invented certainnew and useful Improvements in Freight-Car Doors, of which the following is a specification.

This invention has relation to certain new and useful improvements in doors, and comprises a non-binding freight cardoor, noticeable :because of its simplicity of construction.

The primary object of my invention is to provide a "freight car door which is so constructed as to eliminate binding, and includes means whereby the car door can be readily operated.

It is also within the scope of the invention to provide an extremely simple, compact and inenpensive device of the character specified, which shall be serviceable, convenient and eflicient in its use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, withoutdeparting from the spirit of the invention.

The invention has been illustrated in its prefered embodiments in the accompanying drawing, wherein similar reference characters have been employed to denote corresponding parts, and wherein Figure 1 is a side elevation of a car equipped with a door embodying my invention with parts removed.

Fig. 2 is a vertical section on line 2-2 of Fig. 1.

Fig. 3 is a vertical section on line -3-3 of Fig. 1.

Fig. 4 is a horizontal section on line 4-4 of Fig. 1.

Fig. 5 is a verticalsection on line 5-5 of Fig. 1.

Fig. 6 showsa detail of one of the lower supporting sheaves.

In carrying out the aim of my invention I provide a freight car door A, near the upper edge, with the guide sheaves, 5,

5, each held on a stud 6, these studs in turn Specification of Letters Patent.

Application filed April 7, 1920. Serial No. 371,943.

being held in the strap iron hangers, 7, 7.

therebeing two sheaves located near opposite corners of the door as shown in Fig. 1. while secured to the car above the door openlng, is the upper rail 8, held in position by means of the bolts 9, which enter the car B. V

Extending parallel to the rail 8, is the lower rail 10, fixed in position by means or" the bolts 11, this lower rail giving support to the lower supporting sheaves 12 held in the bracket straps 13, fixed to the lower edge of the door by means of the studs 14. as shown in Fig. 6. These sheaves 12 ride on the supporting rail 10. As shown in Fig. 6 these sheaves 12 are held in the openings 0., of the door A. The straps 13 are U-shaped and are made to clasp the lower edge of the door while the upper strap hangers 7, 7 are also U-shaped and clasp the upper edge of the door A, in the manner shown in Fig. 2. This arrangement makes the removal of the door impossible until the rails 8 and 10 have been removed.

The upper sheaves 5, 5, are partly protected by means of the guard plates 15, which curve over the upper edges of the members 7 the studs 6, 6, being held in the face plates 16 as shown in Fig. 1.

From the foregoing it will be noted that I provide a car door of conventional construction which is supported 'on the rails 8 and 10, by means of the sheaves 5, 5, and 12, 12. These doors are very apt to become jammed or bound, owing to the rough usage to which they are subjected, and in order to provide a means to prevent this binding of the car door, I provide the door with the centrally positioned plate 17 which is rebent to curve over the upper edge of the door A, and gives support to the sheave 18 which rides on the rail 8, the sheave being held on the stud 19, while the lower end is held to the stud 20 giving support to the guiding sheave 21.

Extending crosswise from the studs 19 and 20, are the brace bars 23 and 24 held intermediate of their ends by means of the bolt 25.

Each bar 23 and 24 is bent at its outer end in such a manner that the ends 12, I), extend vertically, so that they can be secured in spaced relation to the bar 27, which forms a continuation of the members 23 and 24, the upper supporting sheave 28 being held port including the crosswise held bars and the connected sheaves 28 and 29.

Secured to'the upper portionof the door opening is the protecting hood C, while protecting the lower rail 16 is the guard plate 34, the door A having the protecting plate 35 which shields the sheaves 12, 12, and 21.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my [invention will be readily understood.

I have entered into a somewhat detailed description of the present and preferred embodiment of my i'nvention'in order toimpart a definite understandingo't' the same. I do not desire, however, to be understood as restricting myself to the exact-construction' shown and described, as various changes or modifications may be-inade inthe form, size, and minor details of construction without departing from the principles or sacrificing any of the advantages of this invention. 1 V v 1 Having thus described my invention, what I claim, and desire to secure by Letters Patent, is:

In combination with a carand its door opening, of two rails skirting said opening in parallel spaced relation, a door, sheaves secured to the lower edge of said door, guide sheaves held to the upper edge of said door, a bar held centrally to said door, a sheave stud in each endof said bar, a supporting sheave in the upper end of saidbar, aguide sheave in the lower end of said bar, said sheaves being held on said studs and a bar having an intermediate straight portion er rangedto clasp over saidrailssaid bar being' continued in two ends which are held crosswise, and fixed to the supporting studs of said centrally held her, all as and for the purpose set forth. 7 1

In testimony whereof I aifix my signature.

EDWARD LAUTNER.
